  • a laser 34 directs a collimated light beam 35 through an illumination lens system 36 onto the sidewall 38 of container 32 .
  • a portion 40 of illumination beam 35 is reflected from the external surface of container sidewall 38 , while a portion 42 is refracted into the container sidewall.
  • a portion 44 is reflected from the internal sidewall surface and emerges from the external surface at a position spaced from reflected portion 40 .
  • These light beams 40 , 44 are directed by an imaging lens system 46 (FIG.
  • An information processor 50 is connected to sensor 48 for scanning the sensor.
  • An encoder 52 is responsive to translation of the container through the inspection station for providing to information processor 50 signals indicative of translation and rotation of the container.
  • Information processor 50 determines the container sidewall thickness, and is adapted to display such thickness at a display 54 and/or to initiate rejection of the container if the sidewall thickness measurement is not satisfactory and/or to supply thickness information to container molding equipment for feedback control purposes.
  • Container 32 is translated and rotated through the inspection station by a conveyor 56 (FIG. 4 ).
  • Conveyor 56 includes one or more linear rails 58 for engaging and supporting the container sidewall, and a linear driven belt 60 for “rolling” the containers along the opposing rails.
  • the containers preferably are translated horizontally and rotated about their vertical axes.
  • Conveyors of this type for simultaneously translating and rotating containers through an electro-optical inspection station are illustrated, for example, in U.S. Pat. Nos. 4,874,940 and 6,172,355, the disclosures of which are incorporated herein by reference for purposes of background.
  • FIGS. 2 and 3 illustrate illumination lens system 36 in greater detail.
  • the output of laser 34 is directed through a cylinder lens 62 , which could be a glass rod for example, which spreads or fans the light in the plane of FIG. 3.
  • a second cylinder lens 64 has its focal point at the divergence point of lens 62 . The result is that the light beam leaves lens 64 as a wide swath with its rays parallel and at approximately the thickness of the laser output.
  • a third cylinder lens 66 has its focal point at the plane of the inner surfaces of rails 58 , and thus at the outer surface of container 32 in engagement with the rails.
  • Cylinder lens 66 thus focuses onto the outer surface of the container a thin line-shaped light beam 35 that has along dimension perpendicular to the axis of the container and parallel to the direction of translation of the container through the inspection station, as best seen in FIG. 3 .
  • imaging lens system 46 includes a cylinder lens 68 and a fresnel lens 70 .
  • the combination of cylinder lens 68 and fresnel lens 70 has an image plane in which sensor 48 is disposed and an object plane colinear with the long dimension of line-shaped illumination light beam 35 at the outer sidewall surface of the container.
  • imaging lens system 46 focuses reflected light beams 40 , 44 (FIG. 5) onto sensor 48 , with the separation between the light beams at the sensor being indicative of the container sidewall thickness.
  • reflected light beam 44 takes the path illustrated at 44 a in FIG. 2, but yields the same wall thickness indication at sensor 48 .
  • FIG. 5 illustrates the same wall thickness indication at sensor 48 .
  • imaging lens system 46 ensures that only the reflected light rays 40 (or 44 ) that are reflected from points perpendicular to the illumination rays, as viewed from a direction parallel to the container axis, are directed onto sensor 48 . That is, only light rays that are incident on and reflected from the surfaces of the container in a plane that includes the container axis are directed onto the sensor. Light rays 40 a and 40 b for example, which are reflected from points non-perpendicular to the illumination light energy, are divergent and directed by lens system 46 away from light sensor 48 .
  • Light sensor 48 preferably comprises a lineal array of light sensor elements, with the array being in the plane of FIG. 2 and perpendicular to the plane of FIG. 4 . Alternatively, sensor 48 may comprise an area array sensor in which only a portion is used for wall thickness measurement in accordance with the present invention.
  • FIGS. 7 and 8 illustrate a modification 36 a to the illumination lens system 36 of FIGS. 2-3.
  • a fresnel or spherical lens 72 is positioned at its focal length from the divergence point of cylinder lens 62 , and at its focal distance away from incidence on container sidewall 38 .
  • Fresnel or spherical lens 72 thus functions both to collimate and converge the light energy from cylinder lens 62 , so that the light energy is directed as a line-shaped beam onto the surface of container sidewall 38 as previously described.
  • FIGS. 9-10 illustrate an apparatus 80 in accordance with a modified embodiment of the invention for translating multiple containers 32 a , 32 b , 32 c between belt 60 and rails 58 through the fields of view of the illumination and imaging systems.
  • the output of laser 34 is directed in an illumination lens system 81 through a positive spherical lens 82 to converge the light to a point at the axis of rotation of a mirror 84 coupled to a galvanometer motor 86 .
  • the light energy is directed through a fresnel lens 88 and a cylinder lens 90 to focus at the plane of rails 58 , and thus at the outside surface of sidewalls 38 of containers 32 in engagement with the rails.
  • the illumination beam 35 a is fairly narrow and incrementally directed across the inspection station by control of galvanometer 86 and mirror 84 .
  • Fresnel lens 88 is placed at its focal length away from the axis of mirror 84 .
  • the divergent beam from mirror 84 thus exits fresnel lens 88 as a collimated bundle, with all rays parallel to the axis of the illumination system and perpendicular to the axes of the containers.
  • Cylinder lens 90 converges the moving collimated beam into a line-shaped light beam at the point of incidence with the container sidewall, as previously discussed.
  • galvanometer 86 and mirror 84 are controlled by information processor 50 (FIG. 1) sequentially to direct the illuminating light energy onto information processor 50 (FIG. 1) sequentially to direct the illuminating light energy onto containers 32 a , 32 b , 32 c within the inspection station.
  • a light source 92 and a detector 94 are coupled to the information processor to synchronize the information processor to entry of containers into the inspection station.
  • Encoder 50 is coupled to drive belt 60 for tracking translation of the containers through the inspection station.
  • galvanometer 86 and mirror 84 are controlled by the information processor first to obtain a wall thickness measurement at container 32 a , then at container 32 b , and then at container 32 c .
  • the measurement beam is then redirected onto container 32 a , which will have advanced and rotated in the inspection station and present a differing sidewall area for thickness inspection. This process is repeated continuously as containers enter and leave the inspection station, so that information processor 50 (FIG. 1) effectively samples sidewall thickness at increments around each container.
  • FIGS. 11 and 12 illustrate an illumination lens system 95 , as a modification to illumination lens system 81 of FIGS. 9 and 10.
  • a cylinder lens 96 is used to convert the laser output beam to a narrow line at the pivot axis of mirror 84 .
  • the beam diverges and strikes fresnel lens 88 .
  • the fresnel lens is placed at its focal distance from the axis of mirror 84 and the opposing surface of container 32 .
  • the collimated light entering the fresnel lens is converged to a narrow line-shaped light beam at the container.
  • the mirror again sweeps the divergent beam across the fresnel lens, and the light exits the fresnel lens parallel to the axis of the system.
  • FIG. 13 illustrates a modification to the embodiment of FIGS. 9-10 in which the imaging lens system 99 includes a photocell 100 , 102 positioned on each side of sensor 48 .
  • the imaging lens system 99 includes a photocell 100 , 102 positioned on each side of sensor 48 .
  • Information processor 50 can make appropriate corrections to control of the mirror.
  • photocells 100 , 102 may comprise cells of an area array sensor disposed on opposing sides of the cell array of primary interest for making container thickness measurements.
